I just read ***another*** article that said a lead substitute has to be used
inM37 series trucks. **************NOT SO***************** These engines
were origionaly built with hardened exhaust valve seats, they appear to be
Stellite) so leaded gas or a lead substitute is not needed. Remember, these
trucks were made to run on whatever quality gas might be available in far

!!! Again, there s no need to use a lead additive or to hunt up leaded gas.
